Stand-alone CoP A.I. and a-life (simulation) overhaul revamping and radically improving every aspect of NPC and mutant behaviour in-game. Changes include everything from complete smart terrain revamp (spawns, function, logical repopulation of all quest-related places), thru NPC and mutant daily behaviours to rank-specific combat skills and habits (diversified aiming skills and reaction times).
All this done for all locations (so Pripyat also got completely overhauled) and perfectly integrated into the storyline and side-quests meaning that (despite such major changes) everything works fine and doesn't get broken.
No other CoP mod ever has touched this subject in such a complete and complex manner - and all this is available to you in stand-alone, 'vanilla-oriented' package making the mod easy to add to your favourite compilation.

- added a new type of custom squad: Monolith Scientific Squads. So now Monolith is divided into two types of groups:

* fighting squads (might regular or vateran) - at day they sit in bases, at night they go out and patrol base vinicity, occasionally venturing futher from it
* scientific squads - at day also sit in bases, at nights go out to 'accesible' (not placed in civilized areas) anomaly fields and scan them

- added optional allowing to control the main respawn rate of smart_terrains (allows to control the overall mood greatly)

- IMPORTANT: SWITCH_DISTANCE (distance at which a-life gets on-line so you can for ex. spot npcs with binocs) is by default set to 300 meters - this shouldnt introduce any poblems but if you experience too much slutter, reduce it in configs\alife.ltx (vanilla value is 150), afterwards you should also reduce the respawn radius in script\smart_terrain.script to the same value as your switch_distance (or slightly lower)

- IMPORTANT: you can increase the overall activity around the Zone by tweaking these values in smart_terrain.script:

local DEATH_IDLE_TIME = 120*60 (squad will not respawn for this time period after death 2 hours by default)
local RESPAWN_IDLE = 14400 (general respawn rate: every 4 hours by default)

- you can turn on the debug mode in configs\plugins\axr_debug_tools.ltx among other things it will allow to see all sts and off-line squad movement on PDA map
- as many stuff as possible was left as it is in vanilla - MSO is supposed to be a sort of 'final patch' to AI and A-life in CoP.

- only AP ammo has tracers for easy recognition (NPCs can and will fire both kinds of ammo now)
